Serial No. 622,053.

To all whom it may concern Be it known that I, ABE E. BERREYESA, citizenof the United States, residing at Oakland, in the county of Alameda andState of Californian have invented new and useful Improvements inInk-Distributers, of which the following is a specification.

This invention pertains to inking mechanism, and particularly to inkingapparatus used with platen presses.

The object of the present invention is to provide an ink dispensingapparatus whereby the ink to be applied to a form in the press isdistributed in substantially uniform thickness during the operation ofthe machine; and to provide a novel, simple and automatic means forobtaining an axial vibration of an equalizing roller.

The invention consists of the parts and the construction and combinationof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which Figure 1 is adiagrammatic view showing the device as applied. Fig. 2 is a plan Viewpartly is section of the inking apparatus. Fig. 8 is an end view of thesame. Fig. 4 is a detail sectional View of an equalizing roller.

In the present embodiment of my invention 2 represents the usual framerollers or distributers which are mounted for rotation in a suitableframe 3 adapted to oscillate between an appropriate ink feedingmechanism, as indicated diagrammatically at 1, and the form indicated at5, the distributers 2 being adapted to move in an irregular line fromthe inking device to the form 5. The rollers 2 are connected to theoscillating frame 3, of which there is one on each side of the press, bymeans of rods 6 slidable in suitable bearings on the frame. The rollersare normally drawn toward the oscillating carrier by means of springs 7surrounding the rods. When the carrier or frame 3 oscillates it carriesthe several independently movable rollers 3 downwardly from the inkingdevice 4 over suitable curved tracks in the frame of the press and on tothe form 5.

To the end of accomplishing an even deposit of ink on the form 5 overthe distributers 2, I provide suitable rollers, hereinafter to bedesignated as equalizers 8, which are adapted to bear longitudinallyupon the adjacent surfaces of pairs of distributers 2; the equalizers 8being positioned above the centers of the distributers 2, and so mountedas to bear with suitable pressure upon the distributers, thus equalizingand distributin the deposit of ink with which the distributers becomecoated as they move over the inking device 4. During the traverse of thedistributers over the inking device 1 to the form 5, the equalizers 8are adapted to rotate upon the distributer and at the same time vibrateaxially in opposite directions, thus insuring an equal distribution ofthe ink from one distributer to the other. Since the severaldistributers 2 are adapted for independent motion, it is desirable to somount and connect them that they may move without restraint orinterference. This may be-accomplished by mounting each distributer 2upon shafts 9 which project sufficiently beyond the ends of thedistributers 2 to be carried in blocks 10 provided on the ends of thereciprocable rods 6. This connection allows the rollers to move towardand from the oscillating carrier or frame 3.

For the purpose of conveniently mounting and dismounting the equalizers8 so as to bear upon the dlstributers 2, appropriately designed saddles11 are employed. These saddles are each pivoted at one end upon one ofthe shafts 9 of the distributers 2. Since the outer distributers 2 maymove independently of the center, when it is necessary to permit thedistance between the shafts 9 to be varied freely, the outer ends of thesaddles 11 are slotted, as at 12, so that the saddles may be passed overthe extremities of the shafts 9 and these may move freely within theslots 12.

The equalizers 8 are mounted for rotation upon spindles 13, providedwith suitable dovetailed lates lt on their extremities, which arelnsertible in dovetailed grooves 15 provided for their reception on thesides of the saddles. The degree of pressure with which the equalizers 8bear upon the surfaces of the distributers 2 may be nicely adjusted bymeans of a set screw or other appropriate device 16 in the saddle 11.The plates 14 are slotted, as at 17, so that they may be adjustedrelatively the set screws 16 to bring the equalizers toward or from thesurface of the distributers 2, as desired. After having once adjustedthe position of the equalizers 8 with regard to the distributers 2 andturned the set screw 16 to lock the plates 14 in the required position,the apparatus may then be operated and the outer distributers 2 maychange their relative position toward the central distributer 2 withoutdisturbing the adjusted position of the equalizers 8.

Between the ends of the distributers 2 and the sides of the saddles 11,which are mounted upon the shafts 9, there may be suitably adjustedfrictional rollers 18 adapted to bear upon the runways formed by or uponthe frame of the press. \Vhen the frame or carrier 3 is oscillated therollers 18 are revolved and transmit motion to the shafts 9 anddistributers 2, and from these a rotary motion is transmitted to theequalizers 8. The equalizing capacity and efiieiency of the equalizers 8is enhanced by causing them to have a longitudinal movement at the sametime they rotate upon the distributors 2. An important feature of thepresent invention is the means whereby this longitudinal vibration orreciprocation of the equalizers 8 is accomplished.

As hereinbefore stated, the spindles 13 are mounted in a stationaryposition upon the* saddles 11, and the equalizers 8, therefore, revolvefreely about the spindles 13. The longitudinal movement of theindividual equalizers is accomplished by mounting upon each spindle 13and within each equalizer 8, which is here represented as a cylindricalshell made up of a number of sections, a worm or screw 20 turnable, butnot slidable, upon the spindle. The screw 20 is in constant engagementwith a nut 21 forming a portion of the equalizer 8, and from the sidesof which project suitable cylindrical sections 22 which areappropriately secured upon cups 23 and 24. The length of the sections 22may vary in differ ent equalizers. The length of the equalizers is alsodetermined by an additional cylindrical section 25 which is adjustableto the cup 23. Upon the extremities of the sections 22 and 25 arescrewed or attached hemispherical caps 26 which bear upon the spindle13. The screw 20 is prevented from longitudinal movement upon thespindle 13 by suitable collars 28 keyed or pinned to the spindle andwhich are provided with slots 29 through which are slidable bolts 30,each secured at one end to respective sleeves 31, rotatably and slidablymounted upon the spindle 13 adjacent the ends of the fixed collars 28.The sleeves 31, carrying the bolts 30 slidable in the collar 28, areadapted to have a slight sliding movement upon the spindle 13 and arenormally pressed toward their respective collars 28 by means of springs,or an equivalent device 32, surrounding the spindle 13 and reactingbetween one end of each sleeve 31 and collars 33 secured upon thespindle 13. Each sleeve 31 is provided with a flanged portion at itsend'opposite the collar 28, and one flanged sleeve 31 is adapted to beengaged by the cup 23 when the cylindrical equalizer 8 is moved towardthe right in Fig. 4:; and the other flanged sleeve 31 is likewiseengaged by the inner end of the plug or member 2 1 when the cylindricalequalizer 8 moves toward the left. The length of the sleeves 31 is suchas to permit the cylindrical equalizer to move a given distance withoutaffecting the position of either of the sleeves 31 upon the spindle 13;but as the cylindrical equalizing shell 8 moves toward the right, justbefore the movement is terminated the cup 23 will pick up the flange onthe adjacent sleeve 31 and move the sleeve sufiiciently to pull the bolt30 from behind a dog 34, formed or secured upon the right-hand end ofthe screw 20. By reason of the engage ment of the nut 21 with the screw20, when the nut 21 is revolved toward the left the cylindricalequalizer will be shifted along the screw 20 toward the right and thescrew is prevented from rotating upon the spindle 13 by reason of theengagement of the dog 34: with the inwardly thrust point of the bolt 30due to the action of its contiguous spring 32. hen the cylinder 8 hasmoved to the right until it engages the flange on the outer end of thesleeve 31 the cup 23 will then have a sliding movement with the sleeve31 upon the spindle l3 sufficiently to disengage the bolt 30 from thedog and release the screw so that thereafter, so long as the cylindricalequalizer 8 is revolving, the screw will revolve in unison therewith.The endwise movement of the nut 21 upon the screw 20 is prevented by theengagement of a stop or pin 35 on the screw 20 with one end of the nut21; and a similar pin or stop 36 prevents the nut 21 from moving beyonda given point which it moves toward the left along the screw 20. hen theequalizing cylinder 8 has been moved to the position indicated in Fig.4, the sleeve 31 (at the left) will be pressed against the end of itsadjacent hub or collar 23 which is fixed upon the spindle 13 by reasonof its spring 32. Since the screw 20 has been release-fl by the oppositebolt 30 and is now revolving with the nut 21, the bolt 30 at the leftwill continue to ride up the inclined surface of its adjacent dog 341-and snap back again against the end of. the screw due to the reaction ofits spring 32. The moment that the cylindrical equalizer 8 starts toreverse its direction of rotation, the dog 341 at the left end of thescrew 20 will revolve into engagement with the inwardly pressed bolt 30and its further rotation upon the spindle 13 will be interrupted so thatwhen the nut 21 revolves clockwise it will then advance toward the leftalong the screw 20. This movement of the equalizer 8 toward the leftwill continue until the inner flange on the plug 24 engages with theflange at the extremity of the sleeve 31 at the left and shifts thesleeve sufiiciently to carry its bolt 30 out of engagement with theadjacent dog 34 in which the screw 20, nut 21 and the cylindricalequalizer 8 will revolve in unison clockwise, and thereafter during theoperation of the oscillating frame 3 whenever the direction of rotationof the equalizers 8 is reversed their axial movement will also bereversed due to the means just described.
